Abstract

Apparatus for treating plastic preforms, with a first transport facility transporting the plastic preforms along a predefined transport path at a first predefined pitch, with at least one heating unit heating the plastic preforms at least at times during their transportation and with a second transport facility arranged downstream with respect to the first transport facility in transport direction of the plastic preforms, which comprises a plurality of holding unit means for holding the plastic preforms and which is suitable and destined to alter a pitch between consecutive plastic preforms. The apparatus comprises a further transport section arranged, at least in sections, in transport direction of the plastic preforms between the first transport facility and the second transport facility, in which a pitch between the plastic preforms is altered.
